cladding painters is a type of metal finishing that uses a layer of material to protect a substrate from corrosion, improve insulation, or give it a more attractive appearance. It’s a common practice in manufacturing and architecture. A variety of materials can be used for cladding, including copper, aluminum, and stone.
Laser cladding is an advanced surface treatment technology that uses a high-energy laser beam to melt diverse alloy compositions and form a specialized alloy-clad layer on the surface of a host part. However, it can generate substantial residual stresses during the rapid cooling and heating stages due to inadequate selection of cladding process parameters and disparities in thermophysical properties between the clad layer and the host substrate. These stresses can result in various types of cracks, which negatively affect the quality and performance of the clad layer.

Among these, hot cracks are caused by the occurrence of coarse brittle phases and impurities in the molten clad layer. This, coupled with thermal cycling and stress concentration due to the shaped orientation of grain boundaries, can cause brittle fracture behavior in the clad layer. Cold cracks, on the other hand, are mainly caused by excessive temperature gradients and the susceptibility of martensite phase transformation at the solidification temperature line. Overlap zone cracks are primarily caused by inappropriate overlap rate selection.
It is also important to note that the color of a clad coating can have a significant impact on its lifespan. Brighter colors tend to fade faster than darker colors. This is an important consideration if you need your cladding to comply with a lease repairing covenant, or for aesthetic reasons.
